FILE-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 318,104 dated May 19,1885.

Application filed October 11,1884. (No model.)

To all whom it may concern..-

Be it known that I, HENRY J. GOSLING, a citizen of the United States,and a resident of Philadelphia, Pennsylvania, have invented a new andImproved FileOutting Machine; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the annexed drawings, making part hereof. 7

The nature of my invention will fully appear from the followingdescription and claims.

In the drawings, in Sheet 1, Figure 1 is a side elevation of my machine;Fig. 2, a front elevation thereof; showing the file-holder, carrier, andits grooved bearing in cross-section, also a cross-section of the screwwhich actuates the carrier. These cross-sections are upon theline 1 2 ofFig. 1. Fig. 3 is a perspective of the anvil {and its block all in onepiece. In Sheet 2, Fig. 4 is a rear elevation of the presser-footmechanism; Fig. 5, a side elevation of the same; Fig. 6, a plan view ofthe slide with its grooved-bearing mechanism for actuating the slide,also the anvil, the block of which is shownin a dotted circular line;Fig. 7, a plan view of the file-carrier, showing a receptacle forreceiving the file-blank; Fig. 8, a horizontal sectional detached viewshowing the position of the tappet, upon the inner end of which the camwhich operates the out ting-chisel acts.

Sheet 1, A, Fig. 1, is the stone base upon which the mechanism rests. BB B are various parts of the cast-iron frame of my ma chine. G is theslide, set in grooves 0. (See Fig. 2.) These grooves are in the upperpart of that section of my frame which I have denominated B.

D is the file-carrier, which is convex for the length of its lowersurface, which sets loosely in a corresponding concave groove passingthe length of the upper surface of the holder D. E is the file-blank tobe cut. The holder. D is secured in place by the set-screw D, whichpasses through a female screw-threaded yoke, D, which in its turn isheld down upon" the upper or outer end of the slide 0.

It will be observed that the upper surface of the part B of my frame hasan upward in-' Cline toward its outer extremity. The grooves beforementioned having the same incline, it follows that the slide 0, carrierD, holder D, and the file upon the carrier traverse up and down at thesame angle.

F is a screw-threaded rod passing through a plain hole in the collar Fat one end, and terminating at the other end in a beveled cogwheel, G,which gears with asimilar cog-wheel, G, set upon a shaft, G, whichpasses through the part B of the main frame, and is actuated by thepulley H and belt H.

I, Figs. 1 and 6, is an ear or lug passing over sidewise from thecarrier 0. The outer extremity of this ear is pierced vertically toreceive a vertically-movable block, J, the lower surface of which latteris provided with a semicircular groove having a female screwthreadadapted, when the block is lowered upon the screwrod F, to engage withthe screw of the latter, whereby the revolution of the screw-rod F willmove the ear-piece I and consequently the slide 0, backward and forwardas the screw turns one way or the other. J is a crank, the shaft ofwhich passes into the interior of the head of the carrier I andterminates in a round plate, in the face of which is set a pin whichsets into a horizontal groove in the opposing face of the block J. Asthe crankshaft is turned, this pin moves upward or downward and raisesor lowers the block J. The length of the slot in the latter permits thepin to slide therein. The pin will have a slight lateral as well asvertical motion as the plate turns withlthe shaft. When the crank J ismoved, the block J will be raised from or lowered down upon thescrew-threaded rod F.

K is the anvil; K, the anvil-block, which is cast or forged preferablyin one piece with the anvil. This anvil-block sets in a hollow space inthe part B of the frame resting below upon the base-stone A. The anvilsets,

up against thelower side of theholder D (see Fig. 2) directly beneaththe point where' the cutter strikes the file. (See dotted lines, Fig.1.) The upper surface of the anvil is slanted at an angle correspondingto that of the lower face of the holder D.

L is the cutter-blade secured in the lower end of the plunger L bysetscrew L. (See Fig. 2'.) Ihave also indicated the position of too thisset-screw by a letter, L, in Fig. 1, the screw itself not showingbecause the plunger L is partially turned whereby the set-screw ishidden. 4

L, Fig. 1, is a setscrew to secure the plunger L in any position towhich it may be turned. This plunger is cylindrical in form and sets upinto a correspondingly-shaped socket in the sliding block L (See Fig.2.) The set-screw L passes through the outside of this block to itsinterior, so as to impinge against this cylindrical plunger, which alsoconstitutes the cutter-holder. The cutter is so turned in the drawingsas to make a diagonal cut upon the file-b1ank. It may be turned so as tomake a cut of any angle upon the blank. The sliding block L has avertical reciprocating motion and sets in a deep dovetailed groove inthe face of the part B of the main frame. This block L is pierced by along vertical slot, M. (See Fig. 2.) The outer end of this steel tappct(see Fig. 8, Sheet 2) is screw threaded to receive a nut, M. The outerface of the block L on both sides of the slot M is serrated, and awasher, M, with an inner serrated face corresponding with and adapted toengage with the serrated face of block or slide L upon both sides of theslot M is set upon this screw-bolt andis held against the face of theblock or slide L" by means of a nut, M, on the screw-threaded end of thetappet M. This tappet is secured in place near its rear end by twoshoulders, N N which are set in two long grooves or recesses in the rearsurface of the block L, which shoulders are adapted to slide up and downtherein. A continuation or projection, N, of the rear end of the tappetsets directly over the cam O, which in its turn is set upon thecam-shaft O. The revolution of the cam 0 gives an intermittent upwardmovement to this projection N of the tappct. As the tappet is securelyfastened in the block L by the nut M, this motion is imparted to theblock L and consequently to the plunger or cutterholder L,andconsequently to the cutter L.

If, through the wearing away of the cutter L, or for any other cause, itbecomes necessary to set the cutter farther down, the nut M is loosenedand the washer M is released from the serrated face of the block orslide L and the block is allowed to drop to the requisite distance, whenthe washer M with its serrated face is again set against the serratedface of block or slide L and the nut M is tightened up, thus securingthe parts in place. As the end N of the tappet rests upon the cam O,theblock or slide L will be lowered, so as to give a lower stroke to thecutter, as desired.

P l? are two metallic disks concave upon their opposite surfaces, andholding between these concave surfaces a rubber cylinder, P. (A spiralor other spring might be substituted.) The disk I? is set by a pin uponthe upper end or face of the block or slide L. A cross-bar, Q, issupported upon columns or standards Q,

Q from the part B of the main frame. A

screw-threaded rod, R, passes through a female screw-threaded hole inthe bar Q, and terminates in a point which sets in a slight depressionor cavity in the top of the disk 1?. The upper end of thisscrew-threaded rod R carries a cog-wheel, R, which engages with acog-wheel, R. The latter cog-wheel is mounted upon the adjusting-rod R,which passes down through the bar Q, and is secured in an uprightposition below by the bearing or lug R Its lower end is polygonal inshape,and is furnished with the wrench R", which engages withitspolygonal end, and by which it is turned. The wrench fits loosely uponit, and when the wrench-handle has moved as far as possible in any onedirection the wrench can be raised up upon the rod 3 to its plainportion and turned around to its startingpoint, dropped intoposition,and another turn taken. This operation can be repeated as longas it is desired to turn the rod 3.

If it is desired to give greater strength to the stroke of the chisel L,the rod R is turned by means of the wrench R in such a manner that themovement of the cogs R and R will force the screwR downward upon thedisk P. This will result in compressing the rubberP, which, by itsspring, imparts the stroke to the cutter through the medium of the slideor block L and chisel-holder L. In order to permit this downward stroke,a cam of such shape is used that after the tappct has been raised to thehighest point of cam O a space will be left between the tappct and thenext succeeding face of the cam to admit of a full downward stroke ormovement of the slide L without having the tappet strike the cam whenthe lowest point of the stroke is reached.

is supported in the upper part, B,of the main frame, and is operated bythe belt S and pul ley S. S is a fixed pulley and Sa loose pulley uponthe shaft 0'. By throwing the belt upon the loose pulley in the ordinaryway the machine is stopped. S is a small pulley lo cated upon thecam-shaft O, which, through the medium of the belt H, actuates thepulley H and its shaft G. This in its turn actuates the cog-wheels G andG,and the'screw-threaded rod F, which, as. explained above, moves thesliding mechanism which carries the fileblank to be out.

In Fig. 5, Sheet 2, and Fig. 1, Sheet 1, T represents hanger or supportattached above to the part B of the main frame, which sustains thepresser-foot and its mechanism. This hanger T is provided with adovetailed groove adapted to receive the sliding tenon T, which slidesup and down in the said groove as the presser-foot mechanism is raisedor lowered. This tenon terminates below in a hollow sleeve, T, cast inone piece therewith. In this sleeve is fitted a short shaft, U, (shownin dotted lines in Fig. 5,) to which shaft is fitted ahead, U. To theunder side of this head is secured The cam-shaft (see Fig. 1) passesthrough and by a screw or bolt the presserfoot U, which is designed tohold the file-blank down while it is being cut. The opposite end of thisshaft is provided with a worm-wheel, V, which is rotated by means of theworm V, which gears with it, and the hand-wheel V, which latter isattached to the worm. The lever W, which is jointed to the main frame byarm W, is operated to raise the presser-foot mechanism by raising thepin Y on the tenon T. This 1ever is raised by means of the rod X, whichis attached below to an ordinary treadle.

By turning the wheel V the presser-foot U, through the worm V,worm-wheel V,and shaft U,is made to bear upon one or the other edge ofthe file by being tilted in one or the other direction, and by theraising of the lever W, through the treadle above referred to, the pin Yis raised, thereby raising the tenon T in its dovetailed groove. Thepresserfoot is thus raised clear of the file-blank, and the latter isreleased.

If at any time it is desired to raise the chisel L up from the blankbeing cut, the foot of the operative is placed upon a treadle similar totreadle X, which is attached to the rod Y, Fig. 2, Sheet 1. This rod isattached to the outer end of a bent lever, Y, which is pivoted at Y tothe main frame. The raising of the outer end of this lever causes thelug Z, which is set up on the same,to strike the lower edge of washer M,and thus raise the slide or block L and the chisel L.

The operation is as follows: The soft-metal file-blank E is laid in itscarrier D with the tang end away from the operative, who sits in frontof the machine, which is to the right in Fig. 1. The block J is thenraised from contact with the threaded rod F. The slide-carrier O is thenpushed down the-incline until the end of the file nearest the operatoris immediately below the chisel L. The presserfoot V is then loweredupon the blank to hold it in place. The chisel is then also let downupon the blank, and the block J is also lowered until its thread engageswith the thread of rod F. Power is then applied through the belt S,which turns the pulley S, which revolves the cam-shaft O, and rapidlyvibrates the chisel, as above described. Theslide or block L is raisedby the cam,and immediately forced down again by the spring of the rubbercylinderI. At the same the small pulley S, by means of the belt H,slowly turns the larger pulley H, from which motion is communicated tothe shaft G and co -wheels G and G. The rod F is thus also slowlyrevolved, which moves the block J slowly up the incline, and the slide0, holder D, carrier D, and the file-blank are also moved slowly up theincline, the file-blank receiving rapid and continuous cuts from thechisel as it ascends the incline. When the cutting is finished,thechisel and presser-foot are raised and the file is released. Anotherblank is then inserted and the operation is repeated.

What I claim as new is 1. In a file-cutting machine, the combina tion ofthe main frame 13 B B and the independent anvil K K, set in a recess oropening in said frame directly beneath the chisel L and resting belowupon the block or support A, whereby the vibrations caused by thedescent of the chisel will be received directly upon the independentanvil and the main support, instead of being sustained by the mainframe, substantially as described.

2. In combination with the main frame B B, B, the plunger L having aserrated face, as shown, adj usting-block M, tappet M, and nut M,projecting through the recess or opening M, the rear end of said tappetcoming in contact with the eccentric 0, whereby said tappet and theplunger L are raised between the strokes of the chisel L, and the depthof stroke of the latter is regulated or adjusted, substantially asdescribed.

3. In a file-cutting mechanism, the presserfoot U, suspended in agrooved hanger, T, from the main frame, provided with a short shaft, U,through the block T, worm-wheel V, worm V, hand-wheel V, whereby thepresser-foot can be inclined and made to bear upon either side of thefile-blank, and the lever W", by the raising of which the operator canelevate the presser-foot and release the file-blank from beneath it,substantially as described.
